Basic Characteristics Of Electric Rotary Table

1. The Motorized Rotation Stage can quantitatively convert the rotary motion of the motor into linear motion, and its energy conversion efficiency can reach 70% (ball screw). This indicator directly increases the load capacity of the electric translation stage.

2. The movement accuracy is high. Positioning accuracy and repeat positioning accuracy can reach the micron level. For example: If the drive motor is a stepper motor, the motor has a pitch angle of 1.8°.

The pitch of the drive screw is 4 mm. It takes 200 turns for the motor to rotate. The linear displacement reflected on the translation stage is the pitch of the lead screw. It is 4 mm. Then the motor

One step per action. The linear displacement of the electric translation stage is 4/200 = 0.02 mm. In addition, the drive of the stepper motor has a pulse subdivision function. Each of the motors can be

The action is subdivided. If 8 subdivisions are used, then each action of the motor. The linear displacement of the electric translation stage can theoretically reach the sub-micron level.

3. Different types of Motorized Linear Stages can be used to achieve high-speed motion. In many applications, it is necessary to increase the speed of the electric translation stage. In this case, the electric translation stage

This is usually the case. The drive is a high-speed servo motor, the drive is a large-pitch screw, or a rack-and-pinion drive. Toothed belt, etc.. Without sacrificing accuracy and smoothness.

Under the premise, the speed of exercise is increased.

4. When the electric translation stage is used in combination, the tool installed on it can reach any point in the three-dimensional space. Complex motion trajectories can be achieved with linear interpolation control.
